TensorRT: IPluginCreator not found in Plugin Registry error when deserializing engine model

Description

I train yolov5 using pytorch, and convert it to tensorrt engine file. When converting I use REGISTER_TENSORRT_PLUGIN(YoloPluginCreator) to register my custom plugin. When loading the engine file, I try to deserialize it but failed, below is the error infomation:

[04/11/2022-20:45:35] [E] [TRT] 1: [pluginV2Runner.cpp::nvinfer1::rt::load::290] Error Code 1: Serialization (Serialization assertion creator failed.Cannot deserialize plugin since corresponding IPluginCreator not found in Plugin Registry)
[04/11/2022-20:45:35] [E] [TRT] 4: [runtime.cpp::nvinfer1::Runtime::deserializeCudaEngine::50] Error Code 4: Internal Error (Engine deserialization failed.)

I have added initLibNvInferPlugins(&gLogger, ""); before serialization but that doesn’t work for me.
